So water should only be coming out of the tell tale and not back down the midsection? I have also seen in a few forums that water may not come out at lower rpms. I don't really believe that this is right but I'm no expert. I can hear air comming out of the mid section but cant feel it at the l/u side of the water tube. Does this reinforce your theory? Just want to make sure before I remove the powerhead! I don't want to mess with to much on the top half because it is running quite good.
